Mcp Failure Lab

Overview

Mcp Failure Lab is a chaos-engineering and resilience-testing toolkit for Model Context Protocol servers. It lets you inject faults, simulate failures, and test how MCP servers handle adverse conditions, helping you build more robust integrations.

The server runs locally via npx -y mcp-failure-lab with no authentication required. It's built on the mcp-failure-lab npm package, currently at v0.6.0, released under the MIT license with source code available at anilloutombam/mcp-failure-lab on GitHub.

Mcp Failure Lab sits in the Development category on mcp.site and works with MCP clients including Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, and Zed. If you maintain this project, claim your listing to verify ownership and keep the information up to date.
